Audio Mixer and Speed Adjust for Squarespace?

Hey Squarespace users!

I have a site that helps music students and we have a lot of play-along tracks for the books. 
 

Does anyone know of a Squarespace plug in or platform I can use on my Squarespace site that will allow students to slow-down the audio to whatever speed they need without changing pitch?
 

I currently have several tracks that are full speed, 80% speed, 60% speed, etc. but it’d be so nice for students to have total control on their end to do whatever speed they need it to be.
 

Any help would be greatly appreciated thanks! 

Hi , if you are  talking about slowing down speed like we do in youtube videos then yes we can do it natively within the squarespace by using custom code. Please do share your website link so we can help you out with it.
